Not able to depend on nlohman_json. #7

Closed ArthurSonzogni closed 5 years ago

ArthurSonzogni commented 5 years ago

Not sure if this is an issue, but I tried different way to depend on nlohman_json. I started first by what is written in the nxxm doc, then more creative idea:

nlohmann_json

{
  "platform": [ "nlohmann_json" ]
}

Then

● [err] Dynamic exception type: std::runtime_error
std::exception::what: platform_deps : nlohmann_json is incorrect, should be formatted as <pkg>::<component> or <pkg>::+<component> .

nlohmann-json::nlohmann-json

{
  "platform" : [ "nlohmann-json::nlohmann-json"]
}

then:

As nlohmann json is hosted on github, I would advice you to use it definitely via the Github dependency retrieval method :

In your .nxxm/deps file

{
  "nlohmann/json" : { "@" : "v3.1.2", "x" : ["benchmarks"] }
}

Dear @ArthurSonzogni,

As discussed on the gitter chat, you could solve this issue with both : 

{
  "platform" : [ "nlohmann_json::+nlohmann_json" ]
}

and 

{
  "nlohmann/json" : { "@" : "v3.1.2", "x" : ["benchmarks"] }
}

Therefore I'll close it. The documentation has been updated here : https://github.com/nxxm/nxxm-docs/commit/ebfb4dc9d40390d2e28283b0b97abce5c02f198b
